Apply the Pythagorean theorem
a^2 + b^2 = c^2
a = 5, b = 13.
5^2 = 25, 13^2 = 169
25 + 169 = 194
square root 194 = 13.928, rounded to nearest foot = 14 ft.
The minimum ladder length required to reach the top of the wall = 14 ft.
The answer is 36. You can multiply top and bottom by 3, or cross multiply and divide.
I think this might be the Answer
Step-by-step explanation:
Sum of −8.46 and 5.31 means we need to add −8.46+5.31.
We know that,
|-8.46| > |5.31|
It means we subtract 8.46 - 5.31
At hundredth place, 6-1 = 5
At tenths place, 4-3 = 1
At ones place, 8-5 = 3
It would mean that, 8.46 - 5.31 = 3.15
8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15
Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".
